Description
The field of this invention is fertilizers.
Fertilizers are materials that are used to supply elements needed for plant nutrition. Fertilizer materials may be in the form of solids, semi-solids, slurry suspensions, pure liquids, aqueous solutions and gases. Fertilizing materials may be introduced into a plant's environment in a number of different ways, including through addition to the soil, through application directly to a plant's foliage, and the like. The use of fertilizers is critical to commercial agriculture as fertilizers are essential to correct natural deficiencies and/or replace components in soil.
In many instances, it is beneficial to apply a fertilizer directly to the foliage of a plant, i.e. to use a foliar fertilizer. Such instances include situations where a given soil has characteristics such that the transport properties of nutrients through the soil are poor. In such instances, the use of a foliar fertilizing composition overcomes the soil disadvantages.
As such, a number of different foliar fertilizer compositions have been developed and/or used with a variety of different types of crops.
Despite the number of different foliar fertilizers that have been developed, there is a continued need to develop new compositions. Of particular interest would be the development of fertilizer compositions that include a minimum of different components, preferably naturally occurring components, where such compositions nonetheless provide for significant enhancement in plant growth.

In practicing the subject methods, the foliar fertilizer composition is contacted with at least a portion of the foliage of the plant for which growth is to be enhanced. By contact is meant that the aqueous fertilizer composition is placed on the surface of the foliage of the plant(s) to be treated, where the term "foliage" is used broadly to encompass not only the leaves of the plant, but every other part of the plant that is not underground, i.e. below the soil surface, such that the term "foliage" includes leaves, stems, flowers, fruit, etc. Contact may be by any convenient methods, including spraying, applying etc.
The amount of aqueous composition that is used during any one application will vary greatly depending on the nature of the plant, the nature of the composition, the environmental conditions, etc. Where crops are treated with the subject compositions, the amount that is applied based on acreage is generally at least about 0.25 to 10 gal per acre, usually at least about 0.25 to 5 gal per acre, and more usually at least about 0.25 to 2.5 gal per acre, where the amount that is applied may be as high as 10 gal per acre or higher, but will usually not exceed about 5 gal per acre.
Depending on the nature of the plant, the nature of the composition, and the environmental conditions, as well as other factors, the foliar fertilizer composition may be applied more than once over a given period of time. As such, the fertilizer composition may be applied daily, weekly, every two weeks, monthly etc.
Where one starts with a parent mix or concentrate, as described above, the subject methods also include a dilution step, in which water is combined with the concentrate in order to reduce the amount of agent in the composition. This dilution step will comprise introducing a sufficient amount of water to the concentrate to obtain at least about a 5 fold dilution, usually at least about a 10 fold dilution, and in many instances at least about a 20 fold dilution.
The subject methods, i.e. foliar application of the aqueous composition, result in an enhancement of growth of the plant that is treated, as compared to a control. By enhancement of growth is meant that over a set period of time, the treated plant attains a higher total mass than the control. The amount of enhancement will typically be at least about 5%, usually at least about 10% and more usually at least about 25%, where in many embodiments the amount of enhancement may be 50% or greater. In many embodiments, the amount of enhancement will be at least about 100%.
A variety of different plants may be treated according to the subject methods, where such plants include both crop and ornamental plants. A representative list of plants that may be treated according to the subject invention is provided in Table 1, infra.
The following is offered by way of illustration and not by way of limitation.
I. Folic Acid Composition
A 1 ppm folic acid aqueous solution (FA 1 ppm) was prepared by combining 1 mg folic acid with 1 L tap water (obtained from the laboratory tap, Tulock Calif. municipal water supply). Similarly, a 2 ppm folic acid aqueous solution (FA 2 ppm) was prepared by combining 2 mg (amount) folic acid with 1 L tap water.
Rutger's tomato seedlings were sprayed with either tap water, the 1 ppm folic acid composition or the 2 ppm folic acid composition at 14 day intervals for 2 months beginning at the 4th leaf stage. 4 sprays were applied over the 2 month period. Plants were then cut at the soil line and air dried for 72 hours. The results are provided in Table 1 below. Weights of plants are expressed in grams.

II. Pyridoxine Composition
A 1 ppm pyridoxine solution (P 1 ppm) was prepared by combining 1 mg pyridoxine hydrochloride with 1 L tap water. Similarly, a 2 ppm pyridoxine aqueous solution (P 2 ppm) was prepared by combining 2 mg pyridoxine with 1 L tap water.
Rutger's tomato seedlings were sprayed with either tap water, the 1 ppm pyridoxine composition or the 2 ppm pyridoxine composition at 14 day intervals for 2 months beginning at the 4th leaf stage. 4 sprays were applied over the 2 month period. The plants were then cut at the soil line and air dried for 72 hours. The results are provided in Table 2 below. Weights of plants are expressed in grams.

III. Composition Having Both Pyridoxine and Folic Acid.
An aqueous solution (FA& P@1) having 1 ppm folic acid and 1 ppm pyridoxine was prepared in a manner analogous to that described above. Similarly, an aqueous solution (FA&P@2) having 2 ppm folic acid and 2 ppm pyridoxine was prepared.
Rutger's tomato seedlings were sprayed with either tap water, the FA& P@1 composition or the FA& P@2 composition at 14 day intervals for 2 months beginning at the 4th leaf stage. 4 sprays were applied over the 2 month period. The plants were then cut at the soil line and air dried for 72 hours. The results are provided in Table 3 below. Weights of plants are expressed in grams.

It is evident from the above results and discussion that useful fertilizer compositions capable of enhancing plant growth are provided. The subject fertilizer compositions are relatively simple formulations in that they include a minimum of agents, and are readily prepared. Despite their simplicity, the subject compositions provide for substantial plant growth enhancement.
All publications and patent applications cited in this specification are herein incorporated by reference as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. The citation of any publication is for its disclosure prior to the filing date and should not be construed as an admission that the present invention is not entitled to antedate such publication by virtue of prior invention.
Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is readily apparent to those of ordinary skill in the art in light of the teachings of this invention that certain changes and modifications may be made thereto without departing from the spirit or scope of the appended claims.
